ABSTRACT:
A keyless entry mechanism for opening a lock, generally comprising a housing, an operating shaft positioned within said housing and operably aligned to extend out of said housing to contact a bolt of the lock, a shaft drive positioned within said housing and operably connected to said operating shaft to extend said operating shaft, and an actuation mechanism operationally positioned within said housing for extending said shaft. The operating shaft is manually retracted and latched against the shaft drive. Upon receiving an actuation signal, the actuation mechanism releases the latched shaft drive allowing it to extend against the bolt and push the bolt into the door. The keyless mechanism simultaneously unlocks and unlatches the door.
